@admkun , those people probably criticizing the illogical premise and how the story was brought on, and yeah, this one is a hot trash, but trash can be readable, just like junk food being edible and enjoyable.
The art is the drawing, it's the artist's effort, the story is the author's effort, especially because this manga is a novel adaptation.
I really doubt anyone who called this trash specifically points them towards the art, so don't lump both together.
